It should come as no surprise to most that Google launched their own programming language. But that slick and clean syntax offers advantages to more than just newbies. Go may be an easy language to pick up, but that brings with it a lack of versatility. Some of the hottest languages on the market pride themselves on their complexity. Choices like Swift and Haskell may be more difficult to learn, but they manage to find their fans by packing in a wealth of smart abstractions that allow coders to achieve complex and clever results with less.
By stripping out this high-level functionality, Go also sacrifices range. Go users can accomplish a lot without having to import or learn complicated secondary libraries.
The standard library that comes packaged with Go is sophisticated without overwhelming, and it reduces the risk of errors from conflicting function names. Take the example of slices. A number of tasks that would require complicated workarounds in other languages can be accomplished with a single line of code through the Go interface.
It will teach you enough Go to be able to write your own tools. Learn faster. Move faster. Go is an open-source programming language focused on simplicity, reliability, and efficiency.
Today, Go is used for a variety of applications like cloud and server side applications, DevOps, command line tools and much more. Python and Go both have a simple syntax and first-party support from all major cloud providers. Both Go and Python are easy to get started with for beginners and are relatively easy to learn.

Their frustration at their toolset forced them to rethink system programming from the ground up, creating a lean, mean, and compiled solution that allows for massive multithreading, concurrency, and performance under pressure.
Running Go on modern hardware—and even inside containers or on virtual machines—can be a real pleasure. Because Go was designed to run on multiple cores, it is built to support concurrency and scale as cores are added. Further, its multithreading capabilities—most specifically, its goroutines—are a surprising and welcome addition to your bag of tricks. These are essentially concurrent functions that run while the rest of the program completes. In other words, you can fire off a goroutine, have it run, and keep going while it and thousands of its brethren process in the background.
Network timeout? Complete database failure? Your goroutine will know, and you can gracefully work around the issue. The main function works just like it does in C. In this code, main fires off a goroutine—indicated by the go keyword —called hello.
The program takes a quick nap and then continues. The program finishes when the main routine wakes up and fires off a Println. The hello function could be anything—a data call, a transaction, a queue entry—and it would run while the rest of the program churns along. Like the aforementioned vine, think of goroutines as little flowers that branch off and die while the main vine keeps going. Want to see it in action? This feature alone is worth the price of admission.
For web apps, goroutines let you run concurrent jobs while avoiding roadblocks. In other words, your program will keep running even if the concurrent processes take longer than expected.
If any Goroutine in that thread blocks, say, waiting for user input, then another OS thread is created and the remaining Goroutines are moved to the new OS thread. All these are taken care of by the runtime and we, as programmers, are abstracted from these intricate details and are given a clean API to work with concurrency.
Want to watch a log? Want to send out regular tweets? Want to manage incoming data from thousands of concurrent users?
Well, Go, can do all of that. Go ensures that your toolbox is compilable across all platforms and on all hardware. You can easily replace your scripting languages with Go and your compiled languages will definitely get a run for their money when stacked against Go solutions. Go is built for software engineering today. Not everything new is great, but when a programming language is designed for exactly the environment most of us use right now—scalable, cloud-based servers that are optimized for performance—a lot can go right.
Go is compilable on nearly any machine, so you can use it to create a full webapp or a tool to clean up incoming data for processing. Like Perl before it, Go is a Swiss Army knife, but one that has stripped off all of the overhead and extra junk that has accreted onto programming platforms over the past few decades.
Go is simple. Go has been different. For folks who already know the basics of programming or a few other languages, learning Go takes a few hours at most.
Go is fast. Take a look at this clever to-do list in Go by Mohamad Fadhil. In a regex test— regex-redux —Go ran in 3. The Go program weighed in at lines of code, while the Java program weighed in at Go is on course to take over many open source and private projects and as it becomes more useful as a standard language for both microservices and the web. It could start replacing less performant solutions like Java and C. Check out GoLang. Many open-source projects e. In contrast, the older projects e.
Go is like chess or, well, the game of Go: it takes a moment to learn and a lifetime to master. I do hope there is indentation in the real code? Also, it seems like many of the fast languages just invoke the PCRE library. And Go is is among the worse languages of those that do. Java might be slow in this benchmark, because it uses its built-in regex library possibly because interop is notoriously bad in Java.
A stack of cocktail napkins is usually faster than most things done in Java. In my experience, Java is one of the Devils we know. Is there a Go for BeOS? However, I think much of the buzz can be summed up in a single word: Google.
